International Patent Application No. PCT/EP2007/010944 was pending as of the filing date of this application. The United States was an elected state in International Patent Application No. PCT/EP2007/010944.

BACKGROUND

1. Technical Field
The present application relates to a method and arrangement for treating bags to be filled with a product prior to filling the bags with a product.
2. Background Information
Background information is for informational purposes only and does not necessarily admit that subsequently mentioned information and publications are prior art.
The present application relates to a treatment arrangement for treating bags or bag packages before the bags or bag packages are filled with a product or ingredient of a product. Such treatment arrangements are used in the food and beverage industries to promote prolonged shelf lives of the products housed in the bag packages or flexible pouches. Additionally, such treatment arrangements are used in the food and beverage industries to restrict or minimize contamination of bag material and/or bag packages after the bag material and/or bag packages have been treated by the treatment arrangements.
Treatment arrangements for treating bags or bag packages may be found in plants for producing bags or bag packages as well as fill and seal bags or bag packages.
The present application relates to a treating device for bag packages, which treating device comprises an entry port, a shaping unit, a filling unit, an exit port and one or more suitable conveying and/or transport elements.
In addition, the present application includes a method for using the treating device.
The present application relates to a sterilizing device for bag packages, said sterilizing device comprising an entry port, a shaping unit, a filling unit, an exit port and one or more suitable conveying and/or transport elements, wherein the entry port includes a UV radiation device or is formed in a substantial manner from said UV radiation device, and said UV radiation device emits pulsed radiation at high power. In addition the present application includes a method for using said sterilizing device.
Sterilizing devices and sterilizing methods are widely known in the foodstuffs industry and the beverage industry. The technology for solid, rigid containers, bottles or the like that have a monolithic body that has been produced by means of blowing or deep-drawing processes is very sophisticated. The surfaces are smooth and substantially without grooves, folds or the like that are difficult to access.
In the case of flexible bag packages, contrary to this, the production processes produce a less smooth surface that is provided with transitions and undercuts. Bent edges, glued surfaces and folded regions that give rise to narrow grooves, folds, edges and/or the like have to be put up with when shaping the bag.
For many liquids and products that are customarily filled into flexible bags, heat treating the filled bag is not desirable as losses in product quality are a consequence of the heat treatment. Consequently, there is great interest in aseptic cold filling. Along with known cleaning steps in water, steam or sterilizing liquids, sterilizing with H₂O₂is very widespread in the area of industrial filling machines for beverages.
Even if this system works in principle, the degree of wetting of the surface to be sterilized in as short a time as possible is limited and an increase in throughput speed with an even lower bacterial count is not achievable with such a system or is achievable with unjustifiably high expenditure.
Sterilizing the foil material used to produce said bags before the processing procedures is also known, as is carrying out the production of the bags as such in a clean-room. Some methods for sterilization involve guiding the foil material in a first step via a wet cleaning station, where the foil is pre-cleaned. The foil pre-cleaned in such a manner is then moved past a UV light source in order to achieve the desired rate of germ killing.
In some methods for sterilization, the pre-cleaning in the first step in these cases also being performed by using a suitable liquid bath. Downstream of this first treatment step, the foil is guided upwards in a shaft so that the liquid can drain away, suitable wipers of the other drying devices being positioned upstream of the UV lamp. This wet, partly mechanical cleaning step is necessary and/or desired in order to remove germs in an appreciable manner in this first step, as the single UV radiation is not sufficient with the band material running at high speeds.
It can easily be understood that this wet, mechanical treatment of the foils is time-consuming and expensive and is responsible, where applicable, for the incomplete removal of liquid residue, incomplete drying and even product degradation.

OBJECT OR OBJECTS

Consequently, it is an object of the present application to disclose the methods and a device that do not have the afore-mentioned shortcomings and that do enable the foil material to be put through at high speeds.

SUMMARY

This object is achieved through the sterilizing device according to the present application for bag packages which include as essential components an entry port, a shaping unit, a filling unit, an exit port and one or more suitable conveying and/or transport elements. The entry port, in this case, includes a UV radiation device or the entry port is formed substantially by said UV radiation device. The UV radiation device is capable of emitting pulsed radiation at high power or at very high power.
In one possible embodiment, the UV radiation device has a radiation output of between 10 and 50 kiloWatts per centimeter squared (kWatt/cm²). In at least one possible embodiment according to the present application, radiation output is within the range of between 15 and 25 kWatt/cm². In one possible embodiment of this present application, this pulsed radiation is the extremely high rate at which germs, bacteria and viruses are killed off. The duration of the radiation pulse is within the range of 100 micro (μ) seconds to 500μ seconds and in one possible embodiment of the present application is within the range of 250μ seconds to 350μ seconds. Through this pulsed input, overheating and, where applicable, subsequent damage to the material of the foil are avoided, restricted, and/or minimized.
The combination of photo-thermal and photo-chemical reactions results in a very sharp rise in pressure and temperature on cell coverings, the UV proportion of the radiation thereby effectively destroying the DNA building blocks, which results in the killing of bacteria, fungus spores and viruses. Without a wet cleaning step and without the use of additional germ-killing substances, a germ reduction of log 3 to log 5 is achieved.
The sterilizing device can be further developed to the effect that gas inlets are provided thereon, said gas inlets leading into the interior space bordering the entry port. By means of said gas supply, excess pressure can be generated in the interior space and the penetrating of pathogenic germs, spores, etc. is reliably inhibited or restricted to an admissible amount.
In one possible embodiment of the present application, the entry port is connected to a gas line and at least one gas outlet is positioned at the entry port, it being possible to generate a gas flow by means of said gas outlet in normal operation in opposition to the direction of movement of the foil. The said gas flow, which flows through the port parallel or substantially parallel to and in the opposite direction to the conveying direction of the foil, along with the blocking effect also has a cooling effect for the foil in the area of the UV radiation.
The sterilizing device can be developed to the effect that a roll reservoir is positioned upstream of the entry port, said roll reservoir being connected to the entry side of the sterilizing device in a fixed or a detachable manner. By means of suitable guiding or conveying elements, the foil can be directed in operation from the roll reservoir into the entry port.
In addition, the present application includes a method for sterilizing bag packages, where the sterilizing device in one of the afore-mentioned embodiment variants is used. In this case,
a) in a first step foil material is directed from a roll or from another reservoir into the entry port,
b) the foil is then exposed to pulsed UV radiation in the region of the entry port at least on one side and in one possible embodiment on both sides,
c) the foil is then formed into bag packages and subsequently
d) said empty bag packages are filled and sealed and, as the last step,
e) the filled bag packages are lifted or conveyed out of the sterilizing device by means of suitable conveying means.
The method according to the present application for sterilizing bag packages can be improved if the internal pressure in the sterilizing device is higher than the ambient pressure and consequently a gas flow is directed through the port from inside to outside. In one possible embodiment of the present application, a gas flow is directed into the interior of the sterilizing device or at least in the flow direction to the exit of the entry port, wherein the gas has clean-room quality. In one possible embodiment of the present application, during the operation, said gas is cleaned by means of filter elements or diaphragm modules before being introduced into the interior space of the sterilizing device.
Various types of films or other sheet materials may be used with the method and apparatus of the present application. For example, the bag packages may be comprised of thermoplastic film, polymer, paper/poly material, polymeric material, polyolefin, polystyrene, polyurethane, polyester, laminates, metallized plastic, metallized paper, plasticized paper, and other types of sheet material.
One example of such a sheet material may include a metallocene polyethylene (mPE), known by the brand name Exceed™, manufactured by ExxonMobil, having the mailing address 5959 Las Colinas Boulevard, Irving, Tex. 75039. Another sheet material may include FLEXOMER™ very low density polyethylene resin, manufactured by The Dow Chemical Company, having the mailing address Dow Ashman Center, 4520 Ashman Street, P.O. Box 1206, Midland, Mich. 48642. Yet another sheet material may include a high performance thermoplastic polyester elastomer, known by the brand name Hytrel® 4068FG, manufactured by DuPont Engineering Polymers, having the mailing address E.I. duPont de Nemours & Co., Wilmington, Del. 19898.
The above-discussed embodiments of the present invention will be described further herein below. When the word “invention” or “embodiment of the invention” is used in this specification, the word “invention” or “embodiment of the invention” includes “inventions” or “embodiments of the invention”, that is the plural of “invention” or “embodiment of the invention”. By stating “invention” or “embodiment of the invention”, the Applicant does not in any way admit that the present application does not include more than one patentably and non-obviously distinct invention, and maintains that this application may include more than one patentably and non-obviously distinct invention. The Applicant hereby asserts that the disclosure of this application may include more than one invention, and, in the event that there is more than one invention, that these inventions may be patentable and non-obvious one with respect to the other.

BRIEF DESCRIPTION OF THE DRAWINGS

One possible embodiment of the sterilizing device according to the present application is represented in which:

FIG. 1 shows a diagrammatic sectional drawing;

FIG. 2 shows a detailed view of the entry port with the UV radiation device in position there; and

FIG. 3 is a block diagram of one possible embodiment of the present application.

DESCRIPTION OF EMBODIMENT OR EMBODIMENTS

FIG. 1 shows a receiving device 2 that is positioned at the entry side of the sterilizing device 1, on which receiving device the foil roll 3, also called the reservoir roll, is mounted. Said foil roll 3 is rotated in a substantially continuous manner during routine operation. The foil 4 is directed via a punching station 5 where necessary and/or desired stability punching can be performed. The foil 4 then runs into the radiation segment 6, which as essential elements includes the entry port 7 and the UV radiation device 8, and as shown in the example a format compensating rocker 9 and suitable guide elements 10 in the form of rolls or rollers.
The bag producing segment 11 connects to the radiation segment 6, in which bag producing segment the empty bag packages are manufactured using suitable means, for example a folding and moulding machine 12. The empty bag packages are transferred into the filling segment 13 and there are filled and sealed and they leave the sterilizing device 1 by means of a port (not shown). In the device represented, a ventilation ceiling 14 extends over the entire length of the sterilizing device 1. The said ventilation ceiling 14 includes a filtering material and serves to generate a laminar, turbulence-free flow, the direction of flow being indicated in a symbolic manner by the arrows 15 that point vertically downwards. The gas outlets are not shown.
FIG. 2 is a detailed view of the receiving device 2, the punching station 5 and the radiation segment 6 with the entry port 7 and the UV radiation device 8. It can be clearly seen that the foil 4 is irradiated on both sides by the radiation source 16 in the region of the UV radiation device 8. In this case, the fan-shaped lines symbolize the UV rays 17. It can also be seen that the horizontal through channel 18 represents the portal into the interior of the sterilizing device 1.
In at least one possible embodiment of the present application, the ultraviolet radiation device or ultraviolet light source 18 may be configured to output radiation or ultraviolet light in the range of about ten kiloWatts per centimeter squared to about fifty kiloWatts per centimeter squared. In another possible embodiment of the present application, the ultraviolet radiation device or ultraviolet light source 18 may be configured to output radiation or ultraviolet light in the range of about fifteen kiloWatts per centimeter squared to about twenty-five kiloWatts per centimeter squared. In another possible embodiment of the present application, the higher range of output of the ultraviolet radiation device or ultraviolet light source may possibly be configured to output radiation or ultraviolet light possibly as high as two hundred fifty kiloWatts per centimeter squared.
FIG. 3 is a block diagram of one possible embodiment of the present application. As seen in FIG. 3, a sheet material may be supplied from a roll or reservoir 3 to an entry point 2 of a sterilization device or treatment arrangement 1. From the entry point 2, the sheet material 4 may be fed to a radiation segment or light-exposing unit 6. The sheet material 4 may be exposed to pulsed ultraviolet light in the segment 6 on one side. In another possible embodiment of the present application, the sheet material 4 may be exposed to pulse ultraviolet on both sides.
Once sterilized and/or treated and/or exposed to ultraviolet light, the sheet material 4 may be transported to a bag-producing segment or a bag forming unit 11. In the bag-producing segment or a bag forming unit 11, the sheet material 4 may then be cut, folded, and/or welded to form a bag or bag package. The bag may then be transported to a filling segment 13, in which the bag may be filled with any of a variety of products or ingredients. Next, the bag may then be transported to a closing segment or sealing unit 50, in which the filled bag or bag package may be sealed, closed, or welded. The filled, closed bag may then be transported out of the sterilization machine 1 through an exit point 51 and to a packaging arrangement 52, in which filled, sealed bag packages may be placed into boxes for distribution.
The sheet material 4, which may later form the bags or bag packages, may be transported in a direction of transport A.
In at least one possible embodiment of the present application, the sheet material 4 may be used in at least the segment 11 and segment 13 within a predetermined time after the sheet material 4 is processed by the segment 6 to restrict and/or minimize contamination of the sheet material 4.
